[boost] [dynamic_bitset] Boost.DynamicBitset is back in business

Hi everyone, I'm happy to share that Boost.DynamicBitset is officially back in business! After some years of relative quiet, I'm resuming active maintenance of the library. My goal is to ensure dynamic_bitset continues to be a reliable and efficient tool for bit manipulation in C++ projects. I'll be reviewing open issues and pull requests, modernizing parts of the codebase where appropriate, and welcoming contributions and feedback from the community. If you've been using dynamic_bitset, have ideas for improvements, or just want to help shape its future, now's a great time to get involved. Feel free to reach out, open issues, or start discussions. Looking forward to collaborating with you all. Best, Gennaro
